WILLIAM WARREN KEY, OF FAYETTEVILLE, ARKANSAS.

REVOLVER.

To all whom it may concern.'

Be it known that I, WILLIAM WARREN KEY, a citizen of the United States,residing at Fayetteville, in the county of Washington and State ofArkansas, have invented certain new and useful Improvements inltevolvers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to revolvers.

Une object of the invention is to insure accuracy in rapid shooting.

Another object is to reduce the strain upon the arm and hand in holdingand firing the ii'evolver.

It is also my ailn to form the handle so that it will not only be inposition to balance the revolver in such a manner as to insure accuracyin shooting but so that it will conform naturally to the hand and willconsequently be restful rat-her than tiresome in the grasp.

Another object is to provide means for carrying an extra. round ofcartridges in the revolver where they will be accessible for immediateuse in an emergency.

A further object is to reduce the length of the revolver over all, ascompared with the length of the barrel, whereby the barrel may be madelonger than in other revolvers without increasing the entire length ofthe weapon.

Another obj ect of my invention is to pro vide improved and tho-roughlyreliable locking means for fastening the breaking por` tions of therevolver together, a secondary lock being employed to prevent theaccidental opening of the revolverwhen in use or when handled by aninexperienced person.

A further object is to automatically lock the trigger when the revolveris open thereby preventing said trigger from being pulled when therevolver is being loaded. This lock is also designed to prevent the userfrom accidentally cooking the revolver, while loading, thus prevent-ingaccidental discharge after the weapon has been loaded and closed.

lt is also my aim to prevent sparks from the cylinder from burning thelinger which is extended along the frame and engaged with the triggerfor tiring the revolver.

Another object is to improve the construc- Specication of LettersPatent.

tion and operation of the trigger mechanism whereby it will be easier tooperate and will not cause the barrel to waver before firing. Inaddition to raising and releasing the hammer, the trigger is designed tounlock the cylinder, to lock the hammer against accidental discharge,and to operate the mechanism for revolving the cylinder.

Another object of my invention is to pro` vide improved operativeconnection between the trigger and hammer whereby the hammer and itsoperating arm cannot become separated or loosened while in the revolverbut may be instantly detached or connected when removed from the gun.This connecting device is constructed with a view to its co-acting withthe trigger for throwing back the hammer, as said trigger is pressedback, for automatically tripping said hammer and for returning saidhammer when released, as in a hammerless revolver. The hammer is alsoadapted to be withdrawn by hand and automatically locked in itsretracted position. The trigger is designedto automatically release thehammer when used in this manner.

A further object is to provide an improved accidental discharge lockoperated by the trigger and serving t-o prevent the hammer from movingforward a sufficient distance to bring its ring pin into contact withthe cap on the cartridge without pressing said trigger.

Still another object is to provide an improved ejector which is simplein construction, reliable and automatic in its operation. The cylinderis retained in position while the ejector moves back and forth as therevolver is opened and closed.

Other objects will become apparent from the following description.

The invention consists in the features of construction and combinationsof parts hereinafter described, illustrated in the accompanyingdrawings, and specified in the appended claims.

Fig. 15 lis a sectional view throughthe fastening device for the upper forward end of the detachable cap,the removal of which converts the revolver from the hammerless to thehammer type, and Fig. 16 is a transverse vertical sectional view throughthe lock which secures the closure of the cartridge storing chamber inthe handle. Y

Referring more particularly to the drawings, 1 designates the lower partof the revolver which carries the firing mechanism, and 2 indicates theupper part including the barrel 3 and cylinder 4. rlhe two parts arehinged together by a pivot pin 5, passed through overlapping pairs ofpivot lugs 1a and 2tl on the parts 1 and 2, and secured by a small screw5, see Figs. 1 and 5.

On the front end of the cylinder there is formed a projecting collar 6normally engaged by a spring-pressed hook 7 whereby said cylinder isretained in proper longitudinal position with respect to the other partsof the revolver but is free to be rotated for successively bringing thecartridges into position for firing. vThis hook 7 is provided with asmall handle or projection S for releasing it from the collar 6 when itis desired to remove the cylinder for cleaning the same.

The ejector rod 9 passes t-hrough the cylinder in the customary way. Theforward end of said rod extends into a chamber 10 in the part 2 of therevolver. Mounted in said chamber, upon the pivot pin 5 as an axis, is asegmental. gear 11 meshing with a rack 12 on the end of the ejector rod.As illustrated in Fig. 5, said segmental gear has a disk-shaped offsetportion 13 arranged between the pivotlugs 2a. This offset portion ordisk has a channel or groove 14 formed in its surface and extendingdiagonally thereof, the pivot pin projecting through its center. Theopposite ends of said channel or groove are partially closed by flangesFig. 9 is a detailed view of the ham- 15 which terminate short of thelower lateral edge of said channel leaving openings 16 at each endthereof. In said channel is fitted a reciprocating plate 17 having anenlarged slot 18 embracing the pivot pin 5. @ne end of the plate isinitially made a little widerthan the channel, and has a slit 2O cutlongitudinally therein extending to the elongated slot 18, leaving aresilient finger 21 which serves to hold the plate in either of itspositions in the channel without employing a separate spring.Projections 22 and 23 are formed on the opposite ends of the plate 17and are capable of being extended through the openings 16 at the ends ofthe channel. The length of the plate, exclusive of its projections, issomewhat less than the distance between the flanges 15 at the ends ofthe channel so that said plate is capable of having a reciprocatingmovement. The length of the projections 22 and 23 is such as to bringone of them flush with the periphery of the offset portion 13 at oneside thereof when the plate is at the end of its stroke in the oppositedirection, that is to say, when the opposite end of said plate is inengagement with the corresponding flange 15. In this position theprojection on the last mentioned end of the plate will extend throughthe corresponding opening 16 beyond the periphery of the disk 13.

The projections 22 and 23 are preferably formed as extensions along thevlower lateral edge of the plate 17. rIhe lower sides of saidprojectionsare straight, as at 24, but their upper sides are rounded or beveled, asat 25, see Fig. 6. lVhen the revolver is closed, the lower projection 22engages a shoulder 26 on the lower part 1 and the projection 23 isarranged in line with the meeting edges of said lower part and the upperpart 2, but said projection 23 is held within t-he periphery of the disk13 by the abutting edges of said lower and upper parts. When t-herevolver is opened, the projection 22, engaging the shoulder 26, holdsthe segmental gear 11 rigid upon the lower part as the upper part isswung away from it. The resnlt is that the ejector rod is movedlongitudinally, by reason of the segmental gear act-ing upon the rack12, to remove the cartridges from the cylinder. When the parts 1 and 2are opened to the fullest extent, the lower face of the upper part, at27, engages the inclined side of the projection 22 and in riding up itforces the plate 17 upwardly until said projection 22 is retractedwithin the periphery of the disk 13 and the projection 23 is extendedbeyond the same along the ripper surface of the part 1 at 28, see Fig.4. The projection 23, engaging the lower part, at 2S, holds thesegmental gear 11 rigid upon said lower part while the upper partY isclosed upon it. lhen the two parts come together in closed position, thelower surface of the Lipper' part, at 29, engages the beveled side ofthe projection 23 and forces said project-ion back into the periphery ofthe disk 13, extending the projection 22 into its initial position. Theoperation of the ej ecto-r is, therefore, entirely automatic. Theformation of the plate 17 with the resilient finger 21 retains it ineither of its two positions until it is moved to the other position inthe operation of opening and closing the revolver as just explained.

The handle 30 is arranged below and intermediate of the ends of therevolver, p referably beneath the cylinder. At the top of the front edgeo-f the handle there is a groove 31, separated by a forwardly projectingpoint 32 from the lower part of the handle, to receive the second fingerof the hand when clasped around said handle. The confining of thisfinger within the groove aids in supporting the revolver in the properlevel position in the hand. The arrangement of the handle below theheaviest part of the gun makes it balance more naturally, removing thestrain on the hand and causing the barrel to normally lie in a levelposition when the revolver is in operation, thereby making itcomparatively easy to aim the weapon and saving considerable time infiring rapidly, as well as insuring accuracy.

The interior of the handle is hollowed out to form a chamber 33 for thestorage of an extra round of cartridges. One side, 34, of the handle ishinged at 35 and constitutes a closure for the chamber 33. Said closureis provided with a hook shaped lug 3G on its inner face and registeringwith a recess 37 in the edge of the handle. Said recess extends down tothe base of the handle and contains a spring-pressed catch 38 having ahook 89 at its upper end adapted to automatically interlock with the lug36 on the closure 34, The lower end of the catch 38 is formed into theshape of a button 40 which is countersunk in the handle, as at 41, spacebeing left to permit the necessary vertical movement of said button forreleasing the latch from the lug o-n the closure when it is desired toopen the latter.

rlhe lower part 1 of the revolver is provided with a finger opening orslot 41 located just behind the pivot pin and ejector disk 13. Saidfinger opening extends parallel to the barrel and into itextends thefinger piece 42 on the forward end of the trigger slide 43 which alsoextends parallel to the barrel. Said trigger slide is normally held inits advanced position by a helical spring 44 housed therein and abuttingagainst a fixed pin 45 passed through a slot 4G in said trigger slidefor limiting the forward movement thereof, as well as for furnishing anabutment for the spring. The bottom surface of said trigger slide ischanneled out at 47 leaving a ratchet tooth or projection 4S facingrearwardly and extending down into the plane of said bottom surface. Thetop surface of the trigger slide is also channeled out at 49, leaving alug 50 extending up into the plane of said top surface.

The rear end of said trigger slide has a bifurcat-ion 51 cut verticallyand centrally thereof and preferably extending forward to the lug 50,leaving two separated lateral walls at the rear end of said slide. Bothof `said lateral walls 52 and project above held in advanced position bya helical spring 58 housed therein and abutting against a fixed pin 59passed through a horizontal slot 60 in said slide. The rear end of thisslide has a vertical bifurcation 61 formed therein with registeringperforations 62 in the sides thereof. Pivotally mounted in saidbifurcation, by means of a pivot pin G3 engaging said perforation 62, iswhat l call a two-part connection between the trigger slide and thehammer. One part 64 of said` connection is pivoted intermediate of itsends in a fork (i5 at the forward end of the other part 66. The forwardend of the part 64 is normally held, by means of a spring 67, up in theplane of the top of the slide 57, and is provided with a ratchet tooth68 facing forward and adapted to engage the ratchet tooth 48 on thebottom of the trigger slide. The rear end of said part 64 normallyextends below the rear end of the slide 57 and its lower corner isrounded off, as at 69, The part 6G is connected at its rear end to thehammer 70 by a safety hinge oint comprising a T-shaped head 71 on thepart GG engaging a transverse slot 72 in the hammer, and the reducedshank 7 3 of said T-sha-ped head confined in a recess 74 in the lowerwall of the slot 72. The opening 75 leading to the slot 72 is of smallerdiameter than said slot. This makes it necessary for the head 71 to beintroduced endwise into said slot, the shank 73, of course, fitting theopening 7 5. It will thus be seen that when the part 66 is connectedwith the hammer and assumes its normal position, there is no chance ofsaid parts working loose or becoming separated in the revolver.

The hammer is pivoted at its lower end upon a pin 7 G. Below said pivot,the hammer is provided with a forwardly extending lug or projection 77.At its upper end, the hammer carries the firing pin 7 S and al shortdistance below it anot-her shorter forward projection 79. On the rearedge of the hammer, near its upper end, there is mounted a pivotedthumb-piece 80 for cocling the revolver when it is used as the hammertype. The hammer is further provided on its rear edge with a hook 81which is adapted tointerlock with the upper end 82 of a verticallymovable spring-pressed retainer 83 for holding the hammer in itsretracted position when cocked by hand. The lower end of said retaineris inclined and extends forwardly, as at 84, into the path of the lowerrounded corner 55 of the lateral wall 52 ofk the trigger slide.

The firing pin 78 extends through an opening 85 in a rigid verticalpartition 86 arranged transversely of the part 1 of the revolver justrearward of the cylinder 4. A vertically movable safety block 97 islocated behind said partition and is pressed do-wnwardly by a spring 88mounted in a slot 89 in said block and abutting against a fixedtransverse pin 90 passed through said slot. The normal position of saidblock, however, that is when the trigger slide is advanced, is raised sothat its upper end reaches above the lug 79 on the hammer and preventsit from being advanced a sufficient distance to bring its firing pininto contact with a cartri dge. Said block is supported in its normalraised position, against the influence of the spring 88, by the inclinedupper edge 54 of the lateral wall 52 at the rear end of the triggerslide. The lower end of said block 97 rides easily up and down upon saidinclined edge The transverse partition 86, located immediately behindthe cylinder, is provided with a vertical slot 91 best illustrated inFig. 12. The bottom of said slot is beveled outwardly and downwardly,as" at 92, for the purpose to be presently explained. j

The cylinder revolving device is made in two parts, the main portion 93thereof being pivoted at its rear end upon a fixed pivot pin 94 so thatit is in line with the vertical slot 91 in the partition 86. The otherportion 95 of said revolving device is mounted telescopically inthe freeend of the part 93. rlihe end of said telescoping part 95 is formed intoa ratchet tooth 96 and below said tooth, said part is beveled off, as at97, to conform to the bottom 92 of the slot 91. `The tele scoping part95 is seated upon a spring 98 which normally presses it outward throughthe slot 91 so that its ratchet tooth 96 will engage one of a series ofratchet teeth 99 arranged in a circle around the middle portion of therear end of the cylinder. rJfhe main portion 93 of the revolving deviceis normally pressed downward by a spring 100 arranged in a vertical slot101 in said part and abutting against a fixed pin 102. The spring 100counteracts the influence of the spring 98 when the revolving device ispassive, that is when the part 95 4is at the lower end of its stroke, byreason of the beveled lower corner 97 of the forward end of said partengaging the beveled bottom 92 of the slot 91 and holding said part 95in a re` tracted position so that its ratchet tooth 96l does not projectinwardly beyond the slot 91 into engagement with the ratchet teeth 99.If desired, a laterally projecting pin 103 vmay be carried by thebeveled lower corner 'wardly through the slot 91 into engagement withone of the ratchet teeth 9 on the rear send of the cylinder 4. The loweredge of the main part 93 of said revolving device is rounded, as at 104,and rests upon the inlclined vupper edge 56 of the lateral wall 53 1 ofthe trigger slide.

The cylinder 4 is locked in each of its positions by a lever 105intermediately pivoted on a fixed pin 106 and having a lug 107projecting upwardly from one of its ends into -engagement with one of aseries of notches 108 in the periphery of the cylinder. These notchesare spaced equidist-ant apart and correspond to the cartridge chambersin the Y cylinder. The lug 107 is preferably rounded `:and is adapted toride in a shallow groove 109 between the notches 108. Said lug 107 isnormally held in engagement with said groove or said notches by a spring110 bearing upon the other end of the lever 105. A

V-shaped lug 111 is formed on the lower edge of the end of the lever105, which is pressed by the spring, and extends into the path of thelug 50 on the trigger slide.

The top of the rear end of the part 1 of the revolver is fitted with aremovable cap 112 for converting the weapon from the automatic type intothe hammer type. Vhen this cap is removed, an opening is left throughwhich the upper end of the hammer projects so that the thumb-piece 80can be engaged for withdrawing the hammer by hand. Said cap is held inplace by a broad hook 113 extending the full width of the interior ofthe chambered rear portion of the part' 1 and projecting from the rearedge of said cap down into the main portion thereof where it engages acorresponding projection or rib 114. VItv will be seen that when saidhook is in engagement with said rib there is :no chance for lateral playof the cap upon the main portion of the revolver. The front end of thecap is secured by means of a headed pin 115 passed through two lateral'projections 116 on said cap and through the partition 86. The head 117of said pin engages the outer face of one of the lateral projections116. The other end of said pin is bored and tapped to receive a screw118, the head of which engages the outer surface of the other' lateralprojection 116 when screwed into the end of the pin 115 whereby said pinis retained in. place and the cap 112 is rigidly secured upon therevolver. Said cap is made to exactly fit and conform to the other partsof the revolver so that when it is in place, the joint between them willhardly be discernible and dust and dirt will be excluded from saidjoint. When the cap is to be removed, it is only necessary to take outthe screw 118 andremove the pin 115, whereupon the hook 113 may bereadily disengaged from the lug 114 when the revolver is opened orbroken.

As hereinbefore indicated, the hinged part 2 of the revolver is securedin closed position upon the main portion 1 thereof by two locks. rllheupper lock consists of a springpressed latch 1197 see Figs. `13 and 14,arranged at the rear end of the part 2 so that it projects over thepartition 86 on the part 1. Said latch is slidably mounted in a recess120 in the rigid portion of the part 2 which extends over the cylinder.The rear end of said latch is formed with lateral projections 121 whichextend islightly beyond the sides of the revolver and are milled orroughened so as to be readily engaged by the thumb andV finger. Avertical passage 122 in the latch 119 has a rearwardly projectingratchet tooth 123 on its front wall. lVhen the revolver is closed, thatis the part 2 is closed down upon the part 1, this ratchet tooth 123snaps into engagement with a hooked projection or lug 124 on the upperedge of the partition 86, thereby locking the two parts of the revolvertoget-her. lVhen it is desired to release the lock, the projections 121are gripped between the thumb and finger and moved forwardly until theratchet tooth 123 is disengaged from the hooked lug 124.

The second or safety lock comprises a pivoted member 125 mounted on themain portion 1 of the revolver just in front of the cylinder and abovethe trigger slide. Said pivoted member is angular in shape, having onearm 126 extending upwardly from the pivot 127 and the other arm 128extending forwardly therefrom. The upwardly cX- tending arm has aratchet hook 129 formed on its forward edge and adapted to engage asimilar but inverted hook 130 on the part 1 of the revolver. A spring131 engages the rear edge of said arm 126 and normally presses the sameforward so that the hook 129 will engage the hook 130 when the part 2 isclosed upon the part l. Milled lateral projections 132 extend from thearm 126 of the locking member 125, slightly beyond the sides of therevolver where they may be engaged by the thumb and finger forretracting and disengaging the hook 129 from the hook 130. When therevolver is opened, that is when the part 2 is spread away from the part1, the spring 131 pressing against the arm 126 of the locking member 125causes the other arm 128 thereof to drop down behind a shoulder 133 onthe trigger slide, thereby automatically locking said trigger from beingpressed while the revolver is in its open position. It will thus be Seenthat the locking member 125 serves the double function of a safety lockfor holding the two parts of the revolver together and also ofa safetylock for preventing the rearward movement of the trigger when therevolver is open.

From the foregoing description, it will be seen, that, when the revolveris closed and the firing mechanism is in its normal position, asillustrated in F ig. 2, the trigger slide and hammer-actuating slide areheld in their advanced positions by their springs, the hammer is in itsadvanced position but held in safety position by the block 87 which issupported in its raised position upon the inclined upper edge 54 of thelat-- eral wall 52 at the rear end of the trigger slide, the cylinder islocked by the lug 107 on'the lever 105 engaging one of the notches 108therein, and the revolving device is in its lowered and retractedposition with its rounded lower edge 104 resting upon the lower'portionof the inclined upper edge 56 of the other lateral wall 53 at the rearend of the trigger slide. It will'be observed that when the parts are inthis position, the lug 50 on the trigger slide is arranged in front ofthe V-shaped lug 111 on the bottoln of the cylinder locking lever 105,and that the ratchet toot-h 48 on said trigger slide is arranged infront of and engaged with the ratchet tooth 68 on the intermediatelypivoted part 64 of the two-part connection between the trigger slide andhammer. When `the trigger is pressed, moving the trigger sliderearwardly, the hammer-actuating slide is moved with it by reason of theen- Iagement of the ratchet teeth 48 and 68. and the hammer is retractedby reason of the connection 66 between it and said hammeractuatingslide. As the trigger slide moves rearwardlv, the lug 50 engages the lug111 on the cylinder locking lever 105 and operates to withdraw the lug107 on said lever from its notch in the cylinder. Thile the cylinder isbeing unlocked in this way. the revolving device 93 has been travelingup the inclined edge 56 of the lateral wall 53 on said trigger slide, sothat by the time the lug on sai d lock h been entirely wi thd rawn fromthe notch in the cylinder, said revolving de- 48 on the trigger slide.

vice has been raised to the rposition indicated in dotted lines in Fig.12 with its end in engagement with one of the ratchet teeth 99 on theend of the cylinder. As the trigger slide travels still fartherrearward, the revolving device travels farther up the inclined edge 56with the resultthat the cylinder is revolved until the next one of thenotches 108 therein is brought into register with the lug 107 on thelocking lever 105.

In the meantime, the lug 50 on the triggery slide has passed the lug 111on the bottom` of the locking lever 105 and vsaid lever has beenreturned to normal posit-ion by the spring 110 so that the lug 107 onsaid leverA engages the notch 108 which has been brought into registertherewith and thus locks the cylinder in position for the firing of acartridge.

All of the operations just described in sequence will have taken placebefore the trigger slide reaches-the limit of its rearward movement.During this operation,y however, the hammer has been swung back therequisite distance and the projection 77 on the lower end thereof hasbeen raisedA into the path of the rear end 69 of the in' termediatelypivoted part 64 of the two part connection between the trigger slide Asthe trigger slide reaches the end of its rear stroke, said lug 77 comesintocontact with said rear end; 69 of the part 64 and raises it therebywithdrawing and disengaging the ratchet tooth.`

and the hammer.

When the pressure of the finger is removed from the trigger slide, itsspring 44 moves.

it forward and returns all of the parts to their initial positions. Indoing so, the safety locking block 97 is pushed up between the partition86 and the lug 79 on the hammer and the cylinder lock is merelywithdrawn momentarily from its Inotch in the cylinder as the lug 50 onthe trigger 'slide passes under the lug 111 on its lock.

As the trigger slide reaches the end of its front stroke, the ratchettooth 48 thereon snaps into engagement again with the The moment these fThe hammer-actuating slide 57 has been.

previously withdrawn with the hammer and the ratchet tooth 68 on thepart 64 dropped below the plane of the ratchet tooth 48 on the triggerslide by the engagement of the projection 77 on .the hammer with therear end of said part 64 in the retracted positions of said hammer andits actuating slide. As the trigger slide reaches the end of its rearstroke, and after its ratchet tooth 48 has passed the ratchet tooth 68,the lower rounded corner 55 on the lateral wall 52 at the rear end ofsaid slide engages the beveled forward projection 84 on the lower end ofthe retainer 83, thereby releasing the hammer which is thereuponimmediately drawn forward for firing by the spring 0f its actuatingslide.

It is obvious that variations may be made in the details of constructionof my revolver, as herein shown and described, without departing fromthe spirit or sacrificing the advantages of my invention. I, therefore,reserve the right to make such changes as fairly fall within the scopeof t-he appended claims.

In order to prevent the finger used for pulling the trigger frombecoming burned by sparks escaping. from the breech of the revolver, Ihave provided a liange 134 eX- tending along the edge of the upper part2 below the barrel and cylinder and above the place occupied by thefinger when the gun 1s 1n use.

I claim:

1. In a revolver, the combination, with a cylinder and hammer, of atrigger-slide op eratively connected with said hammer and having anupwardly and rearwardly inclined portion, a safety block seated uponsaid inclined portion of the trigger-slide and normally interposedbetween the hammer and cylinder, and mea-ns for withdrawing said blockas the trigger-slide is moved rearwardly, permitting t-he block to ridedown said inclined portion.

2. In a revolver, the combination, with a cylinder and hammer, of arigid partition arranged behind the cylinder and having a passage forthe firing pin Yof the hammer, a trigger-slide provided with an upwardlyand rearwardly inclined portion, a safety block normally supported onsaid inclined portion so that it is interposed between the lhammer andpartition for the purpose specified, and means for automaticallydropping said block out of locking position as the :trigger-slide ismoved rearwardly and the blockis permitted to ride down said inclinedportion.

3. In a revolver, the combination, with a cylinder and hammer, of atrigger-slide operatively connected to said hammer and having twoinclined'portions, one extending upwardly and rearwardly and the otherupwardly and forwardly, a safety block supported in normal position bysaid forwardly and rearwardly inclined portion, and a cylinder-revolvingdevice supported upon the other inclined portion whereby the rearwardmovement of the trigger-slide will allow the withdrawal of the safetyblock and will aetuate said revolving device.

4. In a revolver, the combination, with a cylinder and hammer, of atrigger-slide 0peratively connected to the hammer, a cylinder lock, acylinder-revolving device, and a safety block1 all arranged so as to beoperated in the order named, by said trigger slide, as the latter ismoved rearward.

In testimony whereof, I aliiX my signature, in presence of twowitnesses.
